Question

这是我登录页面的代码。但是在用户登录后没有编码的“导航”。需要一些帮助来编码。（导航代码导航到下一个表格）

namespace WindowsFormsApplication2
{
    public partial class Form5 : Form
    {
        public Form5()
        {
            InitializeComponent();
        }

        private void Form5_Load(object sender, EventArgs e)
        {
            using(SqlConnection myconnection = new SqlConnection("Data Source=chariths-bently\\charith;Initial Catalog=emp_mgt;Integrated Security=True"))
            {
            }
        }

        private void login_Click(object sender, EventArgs e)
        {
            if (ok(username.Text, password.Text) > 0)
                MessageBox.Show("Access granted");
            else
                MessageBox.Show("access denied");
        }

        private int ok( string username, string password)
        {
            username.Trim();
            password.Trim();
            SqlDataReader dr = null;
            using(SqlConnection myconnection = new SqlConnection("Data Source=chariths-bently\\charith;Initial Catalog=emp_mgt;Integrated Security=True"))
            {
                myconnection.Open();
                string query = "select * from emp_info ";
                SqlCommand cmd = new SqlCommand(query,myconnection);
                if(cmd.ExecuteScalar () != null)                    
                   return 1;
                else
                   return 0;
            }                
        }
    }
}

private void login_Click(object sender, EventArgs e)
{
    if (ok(username.Text, password.Text) > 0)
    {
        MessageBox.Show("Access granted");
        Form6 f6 = new Form6(); // create your next form instance,(form6, for example)
        f6.Open();
        this.Close();
   }
   ....
}
